본 발명은 나일론 업싸이클 가공방법에 관한 것으로, 보다 상세하게는 폐기되는 나일론 수지 및 나일론 섬유 제품을 회수하여 효율적으로 불순물을 제거하고 물성 별로 분류한 후 특정한 색상과 물성을 보유한 나일론 재생 원료로 재가공하는 나일론 업싸이클 가공방법에 관한 것이다.The present invention relates to a nylon upcycle processing method, and more particularly, it is a method of recovering discarded nylon resin and nylon fiber products, efficiently removing impurities, classifying them by physical properties, and reprocessing them as nylon recycled raw materials with specific colors and properties. It relates to a nylon upcycle processing method.
산업의 발달 또는 생활의 편리함 등을 이유로 현재 합성수지 또는 합성섬유 제품이 많이 사용되고 있으며, 이에 따라 합성수지 또는 합성섬유 폐기물 또한 심각하게 발생되고 있다. 합성수지 또는 합성섬유 폐기물을 처리하는 방법으로 소각하거나 매립하는 방법이 있으나, 소각에 의한 처리는 소각시 유해가스를 다량으로 방출하여 인근 지역의 대기를 오염시키는 문제가 있어 기피되고 있다. 또한, 매립에 의한 처리는 매립지를 구하기가 힘들 뿐만 아니라, 합성수지 또는 합성섬유의 특성상 그 분해 속도가 매우 느리고 침출수에 의한 매립지 오염 문제가 있어 역시 기피되고 있는 방법이다.Due to industrial development or convenience of life, synthetic resin or synthetic fiber products are currently widely used, and accordingly, synthetic resin or synthetic fiber waste is also seriously generated. There is a method of incineration or landfill as a method of treating synthetic resin or synthetic fiber waste, but treatment by incineration is avoided because it emits a large amount of harmful gas during incineration and pollutes the atmosphere of the surrounding area. In addition, the treatment by landfill is not only difficult to obtain a landfill, but also has a very slow decomposition rate due to the characteristics of synthetic resins or synthetic fibers, and there is a problem of contamination of the landfill by leachate.
이에 합성수지 또는 합성섬유 폐기물에 대한 재활용의 필요성이 매우 높아지고 있으나, 아래와 같은 문제점을 내포하고 있다.Accordingly, the need for recycling of synthetic resin or synthetic fiber waste is increasing, but it has the following problems.
첫째, 합성수지 또는 합성섬유 폐기물의 회수와 선별에 많은 설비와 인원이 투입되어야 한다. 회수되는 합성수지 또는 합성섬유 폐기물에는 불순물이 섞여 있는 경우가 대부분이므로 재활용 제품의 품질을 확보하기 위해서는 회수된 폐기물의 선별에 많은 설비와 인원이 필요하게 되어 비용이 높아질 수밖에 없는 문제가 있다. 둘째, 재활용 제품의 품질에 대한 문제이다. 합성수지 또는 합성섬유의 폐기물 회수와 선별에 막대한 설비와 인원을 투입하더라도 재활용되는 원료의 순도가 부족하여 신규 원료와 혼용하여 사용되거나 저급 원료로 사용되고 있다.First, a lot of equipment and personnel must be put into the collection and sorting of synthetic resin or synthetic fiber waste. Since most of the recovered synthetic resin or synthetic fiber waste contains impurities, in order to secure the quality of recycled products, many facilities and personnel are required to sort the recovered waste, which inevitably increases the cost. Second, it is a matter of the quality of recycled products. Even if enormous facilities and personnel are put into waste collection and sorting of synthetic resins or synthetic fibers, the purity of the recycled raw materials is insufficient, so they are used in combination with new raw materials or are used as low-grade raw materials.
현재 각종 산업 분야에서 많이 사용되고 있는 나일론 섬유 또는 나일론 수지 또한 재활용이 가능한 소재이지만, 이러한 문제로 인하여 재활용에 어려움이 있다. 특히, 나일론 수지 제품의 경우 유리 섬유나 다른 합성수지와 혼합되어 사용되는 경우가 많아 완제품을 해체하거나 불순물을 선별하는 작업이 반드시 선행되어야 하고, 나일론 6과 나일론 66은 물성이 전혀 상이하여 나일론 섬유 또는 나일론 수지 폐기물을 원재료에 따라 부가적으로 선별해 주어야 한다.Nylon fiber or nylon resin, which is currently widely used in various industrial fields, is also a recyclable material, but it is difficult to recycle due to this problem. In particular, nylon resin products are often mixed with glass fibers or other synthetic resins, so dismantling the finished product or sorting out impurities must be preceded. Resin waste should be additionally sorted according to raw materials.
본 발명은 회수되는 폐기되는 나일론 수지 및 나일론 섬유 제품을 수집하여 효율적으로 불순물을 제거하고 물성별로 분류한 후 특정한 색상과 물성을 보유한 나일론 재생 원료로 재가공하는 나일론 업싸이클 가공방법을 제공하는 것을 목적으로 한다.The present invention aims to provide a nylon upcycle processing method that collects recovered and discarded nylon resin and nylon fiber products, efficiently removes impurities, classifies them by physical properties, and then reprocesses them into nylon recycled raw materials with specific colors and properties. do.

이때, 상기 제1 단계는, 입고된 나일론 폐자재 벌크에서 불순물을 선별하여 제거하는 제1-1 단계; 및 불순물이 제거된 나일론 폐자재 벌크에서 나일론 6과 나일론 66을 선별하여 분류하는 제1-2 단계;를 포함하는 것을 특징으로 한다.In this case, the first step may include a step 1-1 of sorting and removing impurities from the stocked nylon waste material bulk; and a 1-2 step of sorting and sorting nylon 6 and nylon 66 from the bulk of the nylon waste material from which impurities have been removed.
또한, 상기 제1-1 단계는, 입고된 나일론 폐자재 벌크의 샘플을 일정 온도 이상으로 연소시킨 후 잔류량과 잔류율에 따라 불순물 함유 여부를 판단하는 애쉬 테스트 과정을 포함하는 것을 특징으로 한다.In addition, the step 1-1, after burning a sample of the stocked nylon waste material bulk above a certain temperature, characterized in that it includes an ash test process of determining whether impurities are contained according to the residual amount and residual rate.

이하에서는 본 발명의 구체적인 실시예를 첨부된 도면을 참조하여 상세하게 설명하도록 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1을 참조하면, 본 발명의 일실시예에 따른 나일론 업싸이클 가공방법은 입고되는 나일론 폐자재 벌크에서 샘플을 채취하여 나일론 폐자재 벌크에 유리섬유나 금속 등과 같은 불순물이 섞여 있는지 확인하는 단계로 시작된다. 나일론 폐자재 벌크에 불순물이 섞여 있는지는 일일이 육안으로 확인할 수도 있겠지만, 샘플을 채취하여 샘플에 대한 애쉬 테스트를 진행하여 불순물이 섞여 있는지, 어느 정도의 비율로 섞여 있는지 확인하는 것이 바람직할 것이다.Referring to Figure 1, the nylon upcycle processing method according to an embodiment of the present invention is a step of checking whether impurities such as glass fibers or metals are mixed in the nylon waste material bulk by collecting a sample from the received nylon waste material bulk. begins Although it is possible to visually check whether impurities are mixed in the bulk of the nylon waste material, it would be desirable to collect a sample and conduct an ash test on the sample to check whether impurities are mixed in and to what ratio.
애쉬 테스트는 샘플을 일정 온도 이상으로 가열하여 나일론 소재를 연소시킨 후 남은 잔류량에 따라 불순물 함유 여부를 확인하는 테스트이다. 아래 표 1은 특정 나일론 폐자재 벌크의 샘플에 대한 애쉬 테스트를 수행한 결과이다.The ash test is a test to check whether or not impurities are contained according to the residual amount after burning the nylon material by heating the sample to a certain temperature or more. Table 1 below shows the results of performing an ash test on a sample of a specific nylon waste material bulk.
상기 표 1에 따르면 애쉬 테스트 결과, 애쉬 잔류량이 0.007g으로 잔류율은 0.23%으로 양호하였으며, 이에 따라 입고된 나일론 폐자재 벌크에는 불순물이 거의 섞여 있지 않은 것을 알 수 있으며, 별도의 불순물 제거 단계를 거치지 않고 다음 단계로 진행하게 된다.According to Table 1, as a result of the ash test, the residual amount of ash was 0.007 g and the residual rate was 0.23%, which was good. Accordingly, it can be seen that the bulk of the nylon waste material received was hardly mixed with impurities, and a separate impurity removal step was performed. It will proceed to the next step without going through it.
아래 표 2는 다른 특정 나일론 폐자재 벌크의 샘플에 대한 애쉬 테스트를 수행한 결과이다.Table 2 below shows the results of performing ash testing on samples of other specific bulk nylon waste materials.
상기 표 2에 따르면 애쉬 테스트 결과, 애쉬 잔류량이 0.207g으로 잔유율은 6.73%를 기록하였는바, 입고된 나일론 폐자재 벌크에는 유리섬유나 금속 등과 같은 불순물이 다소 섞여 있을 가능성이 높으므로 별도의 불순물 제거 작업을 수행하도록 한다.According to Table 2, as a result of the ash test, the residual amount of ash was 0.207 g and the residual oil ratio was 6.73%. to perform the removal operation.
이와 같이 입고된 나일론 폐자재 벌크에 대한 불순물 함유 여부를 확인하고 불순물 제거 작업을 수행한 후, 나일론 폐자재 벌크에 나일론 6과 나일론 66이 혼재되어 있는지를 확인하는 작업을 수행한다.After confirming whether the bulk of the nylon waste material received in this way contains impurities and removing impurities, it is performed to check whether nylon 6 and nylon 66 are mixed in the bulk of the nylon waste material.
나일론 6과 나일론 66은 육안으로 구별하기 어려우므로 별도의 확인 작업이 필요하며, 본 발명의 일실시예에서는 나일론 6과 나일론 66의 용융점 차이를 이용한 멜팅 테스트를 통하여 판별하도록 하였다.Nylon 6 and nylon 66 are difficult to distinguish with the naked eye, so a separate confirmation operation is required.
즉, 입고된 나일론 폐자재 벌크의 샘플을 나일론 6의 용융점인 약 230℃ 보다는 높으며, 나일론 66의 용융점인 약 275℃보다는 낮은 온도로 가열하여 샘플의 용융 정도나 형태에 따라 나일론 6과 나일론 66이 혼재되어 있는지를 판별하도록 한다. That is, a sample of the stocked nylon waste material bulk is heated to a temperature higher than the melting point of nylon 6, about 230° C., and lower than the melting point of nylon 66, about 275° C. to determine if they are mixed.
도 2에는 이와 같이 멜팅 테스트를 수행한 결과물의 사진이 도시되어 있는데, 도 2(a)와 같이 샘플이 전체적으로 일정하게 용융되어 있는 경우에는 입고된 나일론 폐자재 벌크에 나일론 6만이 함유되어 있는 것으로 판별한다. 그러나, 도 2(b)와 같이 샘플이 일정하게 용융되어 있는 것이 아니라 용융되지 못한 덩어리가 섞여 있는 경우에는 입고된 나일론 폐자재 벌크에 나일론 6과 나일론 66이 혼재되어 있는 것으로 판별하도록 한다.FIG. 2 shows a photograph of the result of performing the melting test as described above. When the sample is uniformly melted as a whole as shown in FIG. 2(a), it is determined that only nylon 6 is contained in the stocked nylon waste material bulk. do. However, if the sample is not melted uniformly as shown in FIG. 2(b), but a lump that has not been melted is mixed, it is determined that nylon 6 and nylon 66 are mixed in the stocked nylon waste material bulk.
이와 같이 나일론 6과 나일론 66이 혼재되어 있는 나일론 폐자재 벌크는 별도의 선별 단계를 거쳐 나일론 6과 나일론 66의 혼입 생산을 방지하도록 하여야 한다. 이러한 선별 작업은 역시 나일론 6과 나일론 66의 용융점 차이를 이용하여 수행할 수 있을 것이다.As such, the bulk nylon waste material in which nylon 6 and nylon 66 are mixed must undergo a separate screening step to prevent mixed production of nylon 6 and nylon 66. This sorting operation could also be done using the difference in melting point between nylon 6 and nylon 66.
나일론 폐자재 벌크에 대한 불순물 제거와 종류별 선별 작업이 완료된 후에는 나일론 폐자재 벌크의 샘플에 대한 점도 테스트를 수행하도록 한다. 입고되는 다양한 나일론 폐자재 벌크는 다양한 점도를 가지고 있을 것인데, 이를 고려하지 않고 그대로 용융하여 최종 나일론 재생 원료로 가공하는 경우 물성이 균일하지 못하게 되어 품질에 문제가 발생할 것이다.After the removal of impurities and sorting by type of the nylon waste material bulk is completed, a viscosity test of the nylon waste material bulk sample should be performed. The various bulk of nylon waste material received will have various viscosities, and if it is melted without taking this into account and processed into the final nylon recycled raw material, the physical properties will not be uniform and quality problems will occur.
이를 방지하기 위하여, 입고되는 나일론 폐자재 벌크별로 점도를 테스트한 후 이를 분류한 후, 다수의 나일론 폐자재 벌크를 선택적으로 블렌딩하여 최종 나일론 재생 원료로 가공하여 물성이 균일하도록 하는 것이 바람직할 것이다.In order to prevent this, it would be desirable to test the viscosity for each incoming nylon waste material bulk and classify it, then selectively blend a number of nylon waste material bulks and process it into a final nylon recycled raw material so that the physical properties are uniform.
아래 표 3은 입고된 다수의 나이론 폐자재 벌크의 샘플들을 각각 용융하여 점도 테스트(Melt Index Test)를 수행한 결과이다.Table 3 below shows the results of performing a viscosity test (Melt Index Test) by melting each of a plurality of stocked nylon waste material bulk samples.
상기 표 3에서 알 수 있듯이 입고되는 나일론 폐자재 벌크에 따라 어느 벌크는 높은 점도를 가지고 있고 어느 벌크는 낮은 점도를 가지고 있어, 균일한 물성을 보이지 못하고 있다.As can be seen from Table 3, some bulks have high viscosity and some bulk have low viscosity depending on the bulk of the nylon waste material to be stocked, and thus, uniform physical properties are not shown.
아래 표 4는 점도별로 분류된 나일론 폐자재 벌크들을 선택적으로 블렌딩한 후 각각의 샘플들을 추출하여 점도 테스트를 수행한 결과이다.Table 4 below shows the results of performing a viscosity test by selectively blending nylon waste material bulks classified by viscosity and then extracting each sample.
상기 표 4에서 알 수 있듯이 나일론 폐자재 벌크를 선택적으로 블렌딩한 후에 각각의 샘플들은 균일한 점도를 나타내고 있다.As can be seen from Table 4 above, each sample exhibited a uniform viscosity after selectively blending the bulk nylon waste material.
한편, 입고된 나일론 폐자재 벌크의 점도에 따라 분류하는 것 외에도 색상에 따라 분류하는 것도 필요할 것이다. 이는 색상 별로 분류된 나일론 폐자재 벌크들을 선택적으로 블렌딩하여 특정 색상의 최종 나일론 재생 원료를 생산하기 위한 것이다. 만약, 나일론 폐자재 벌크들을 선택적으로 블렌딩하여도 특정 색상을 구현하기 어려운 경우에는 첨가제로써 특정 색상의 안료를 혼합하여 가공하도록 한다. 나일론 폐자제와 혼합되는 첨가제로는 안료 이외에도, 특정 성분의 오일이나 다른 합성수지 재료, 유리 섬유 등이 사용될 수가 있을 것이다.On the other hand, in addition to classification according to the viscosity of the received nylon waste bulk, it will also be necessary to classify according to color. This is to selectively blend color-sorted nylon waste bulks to produce a final recycled nylon material of a specific color. If it is difficult to realize a specific color even by selectively blending bulk nylon waste materials, a pigment of a specific color is mixed as an additive to be processed. As an additive to be mixed with the nylon waste material, in addition to the pigment, a specific component of oil, other synthetic resin materials, glass fibers, and the like may be used.
